Hand Sounding Machine

A hand sounding machine, also known as a hand sounder or hand-held sounder, is a tool used in construction and engineering to measure the depth of water or the thickness of a material. It consists of a long, slender rod with markings or measurements along its length.

To use a hand sounding machine, the rod is lowered into the water or material being measured until it reaches the bottom or the desired depth. The user then reads the measurement on the rod to determine the depth or thickness.

Hand sounding machines are commonly used in various applications, such as determining the depth of water in wells, measuring sediment levels in rivers or lakes, and assessing the thickness of asphalt or concrete pavement. They are portable and easy to use, making them a convenient tool for fieldwork and on-site measurements.
